Real lightsaber idea: electron beam saber

[GDuff123]

What about plasma subjected to an electromagnetic current via electromagnetic coils? Somewhat like NASA's new plasma shield prototype(s) and design(s). Plasma is contained to a limited area, the hilt would be shaple like a "Y", With the top part of the "Y"(The "V" of the "Y", if you will) Used to provide a triangular(isoceles) shaped blade and contain the coils/magnets. The energy source...I am not sure.

I have no clue if any of this would work, just looking for opinions?

[BlakOpzDragon]

"you can not make the electromagnetic field of electrons stop at a certain point for a real light saber unless stop by another piece of matter it is impossible to make a real lightsaber" But what about a "Beam Sword" like in No More Heroes? Not a Lightsaber, but a sword with a Support Rod and the other magnetic disc to stop it. Then the Electromagnetic Field of electrons will stop, thus having a "cutting side" and a "blunt side". Once the Support Rod breaks, the blade is no longer workable, tho

[TommyBahama101]

Thanks for posting this. I'm kind of a researcher myself, and this is similar to what I'm trying to accomplish. It gave me an idea of what I've been looking for, thank you.

[AznFiter]

Why won't this theory work?

[AznFiter]

How would the light be stopped? It would also go on forever, right?

[TommyBahama101]

@AznFiter The electrons loop round back to the hilt due to it's electromagnetic metal. And the light coming from the hilt would only illuminate the electrons so no, it wouldn't go on forever.

[cantshockthis]

im currently 21 and im gonna try to make this, i loved star wars my whole life and dont have any family, plus my somewhat freind is rich and he will provide money. I have nothing to lose if anything goes wrong

[kiball09]

this should come in SWTOR collectors edition box set

[pitsahat2]

Right now there is no energy storage capable of providing the energy needed for this to work...well not portable at least.

[patrickwellerwrites]

@pitsahat2 what about carbon nano tubes?

[kramerthegamer1]

Step three is problematic as producing a field like that would be very energy intensive. Also, stopping the beam seems like a problem to me. What would you do about the beam of electrons heading back towards the hilt? Just turn them around in a never ending loop? Someone could easily kill you by simply throwing a magnet at your lightsaber, causing your beam to not form a loop and sending a jet of high energy particles in a direction (possibly at you). Flawed, but good theorycrafting

[Gothic238]

Very clever idea! If you invest a lot more research (not meaning to sound like a snob, I'd have know idea what to do!) and money you never know, we might be looking a lightsabers as a possibility!

[OOHSLAX25]

i wonder how much money you would get for being the first human alive to create a lightsaber

[HHHdahman]

Just buy one from wal mart.

[Takato142]

Suprisingly enough, this is entirely theoretically possible. Most of youtube videos are bullshit. Great idea with this.

[cabouaf]

would this realy work?

[Hidd3nGruntz]

STEP 8: WHERES MY LIGHT SABER ALREADY?

[LOOTS243]

@kaviilaugh yes, because the magnets has it's "own" type of field...

[bjggjb]

What I don't understand is, WHAT'S THE FUCKING POINT OF A LIGHTSABER, even if it is possible? Unless "The Force" exists (it doesn't BTW) you'd lop your own limbs off under the stress of combat (unlike a normal sword, there's no counter-weight... it would be like swinging a flashlight around!)

Also, let's face the facts. Give me 10 feet of distance and my 12-guage in my hands, and you're a deader if you come at me with your goofy, "cool" lightsaber (unless you're a Jedi and that's pure fantasy.)

[Gothic238]

@bjggjb I agree with that, but if they were made they would probably be used as a universal cutting tool for the army, to replaces combat knives, glass cutters, welders etc.

[lesty40]

epic fly swat B)

[squagglenater]

howcome no one trys to build something like this im 14 so dont say me

[xmasterfunk]

what about the power crystal were does that fit in?

[GiantTurtleWave]

Wow, science actually made something GOOD

[slipyourhips]

@GiantTurtleWave yeah because cars, planes, space shuttles and heart monitors suck

[GiantTurtleWave]

@slipyourhips most certainly XD im just kidding bro

[lenzub]

Electrons wont just go back because of magnets when you put the magnets there chances are all the electrons will just fly into random directions but it is a good fake idea I guess if they did work that way. If it was this easy to think of how to do it there would already be real light sabers like 30 or 40 years ago.

[erererer2]

could it be possible that one day we c ould have guns that fire plasma

[wrestlingchamp526]

so overall would it ever be possible to actually make one of these?

[marcheseDS]

The ideal would be something (em field?) strong and controllable enough to ionize surrounding air, capture and enclose the electrons in the blade and at the same time keeping the ions out of it. This will make the energy consumption much lower unless you are actually cutting something (thus needing to restore the electrons in the blade)

[versuchsnich]

I'm interested of video-responses (if there would ever be any) which show these lightsabers xD

[MrTTE1]

i wonder it this would really work

[thundermoon96]

and on a nother note you wuld need somthing to slow down the molicules to a sertain lingth so they don't go on for like 10-20 feet.

[thundermoon96]

you know this makes a lot of sence kind of like my idea of a hover board just with all due respect i'm not stupid enuf to tell the whole world the plans.

[SuperWario094]

i rather have a phaser and transporter than a lightsaber

[1AceMoneyMaker]

ok if this would work then every star wars fan would get one, then the streets, halls of elementry, middle, and high schools would be drenched in blood :)

[marcheseDS]

@1AceMoneyMaker No, more likely full of scattered body parts...high energy blades cut and cauterize (in every movie :) )

[5dmc1]

ok, I am impressed, now build it :)

[avatar2164]

did you know this information or got the information out of the internet?

[pyromaanisi]

i've heard that the army have one of these but it doesn't cut like in the movies instead it cuts slow...

[Parastalysis]

im working on it right now, it wont be done till july but i will post a video asap

[LamboAnt7]

This actually sounds feasible, great idea!

[Parastalysis]

The problem with light sabers is that heir blade is super heated plasma with a super cooled plasma layer over it. the super cooled plasma layer acts as a solid and is reflective while the inner layer burns. its impractical with the technology we have now, but i designed a light saber that just might work. im gonna post a video soon as its built.

[mewmaster151]

@Parastalysis more data please!!

[Parastalysis]

@mewmaster151 I came up with a couple other designs to, ill make videos once their built. Right now im getting some more money to build them first so it might take a couple months but I will have them built soon enough. If you want feel free to email me and I can give you an update with it every now and then till its complete. and feel free to ask any other questions. I might start a blog for this stuff soon.

[MrBOSNASARAJEVO]

it works but it is hard to cut things onley cuts plastick

[MrBOSNASARAJEVO]

aj nead a vacuum

[balticterra]

i dont think it can work at all becouse electrons and positrons cant be controled in air they would just spread evereywhere

there would be a electromagnatic field needed to contain the energey in order to keep it in the shape of a blade .

riight ?

[MrBOSNASARAJEVO]

comon aj nead a vacuum

[MrBOSNASARAJEVO]

anybody knows where to get vacuum

[MrBOSNASARAJEVO]

dud i will trie to make one

[mrawesomenessssss]

wow this would suck if someone did make it. im moving to alaska if so lol

[Bleuesoul89]

you can not make the electromagnetic field of electrons stop at a certain point for a real light saber unless stop by another peice of matter it is impossible to make a real lightsaber

[Liqliq888]

where does the beam stop

[RandalllFlagg]

Close.

But electrons are negatively charged. The thing wouldn't cut through any matter.

Positrons, however..

Cut through all forms of matter and would deflect another positron blade.

Remember basic physics: Like charges repel each other.

[kostantinos1997]

If someone make it, it will be a big step for humans

[sickboy1138]

this is an interesting idea for a saber. unfortunately ... the power source required for this and any other idea for a physical energy blade would not fit inside a hilt

[LifeLongGamer]

@sickboy1138 Not yet anyway :)

[shadowxbreaker1]

wat if the magnetic field would ever fail

??

[pwnproof]

then the beam would keep going

[pokezach100]

I would definitely get one of those

[sebastianseveso]

do it, then we'll talk =)

[zooaa]

lol it would be illegal to have one cause it could cut people in half example: little kid has one, brother bumps into him, lightsaber goes flying and goes through dads head then uber chaos ... imagine on the side walk with millions of people lol

[obewong]

This would probably work best if you have a mini black hole in the handle sucking the light back in, instead of the magnet. This would also probably assist in performing time-travel and telekinetic enegy abilities and other jedi tricks. Probably explains why Obi-wan just disappeared like that too! :) Pulling my television apart as we speak!

[hillset]

Are you serious douche bags... this is actually a very scientifically sound attempt at recreating something from a movie... that is technologically years ahead of our capability of manufacturing. Give this guy some credit. That took some thought... unlike the comments you have posted...

[SirQuackenbush]

for the blade to be shorter he should add some kind of vacume forcetop shorten the blade

[shadowromeo22]

well electron are full of energy so instead of cutting through stuff it might create tiny explosions

[kaminari47]

interesting.

[OnMyWay2TokyoU]

Although in space, the beam would create a nice light show, since there are no particles for the electrons to bound with in space, since space is a vacum, it would mean that the light would go on until it found something to bound with. Meaning that the light saber would end at the regualer point, but that a beam of light would go on for light years. Can anyone say Line of light in space?

[OnMyWay2TokyoU]

However, you wouldn't even need magnets to make this real, the Sonic generator would cuase the electrons to basically uncharge at a certain distance, and thus makeing the beam stop. So really all you would need is the electrons, and a sonic wave, and bam, problem solved. BTW, most, if not all of Lucas' ideas are based in some part of truth, all fiction is. Plus the sonic wave would increase the cutting power of the blade, and also grant the usage underwater, or in space. Although...

[OnMyWay2TokyoU]

It would work, i am an engineering major, and all of that sounds feasible. however MnisthitiMo is right, another magnetic field, of course strong enough, would disrupt the flow of electrons, and could even kill the wielder, let alone other people. However, A sonic wave generator would actually stabilize the magnetic force, and even if it cut through a magnet, it wouldn't affect the flow, because of the sonic waves keeping the particle within thier boundary, and with that you could even...

[steven9543456401]

just imagine what happens when terroists have it D:

[GJGRIFFITHS0628]

Didnt some one in america a few years back do something with a powerful tubed light and petrol to make a light saber but it blow up after about 2 seconds of bein plugged in I've been trying to find a video or newspaper article for a while now just wondered if any1 else has heard this

[Nypopsicle18]

If only some douche with 60 billion dollars would make a show and test out ideas like this. Couchbillgatescough. Oh well :)

[MnisthitiMo]

It would suck if you had anything magnetic around that.

[shihtzusrool]

yeah but how would you even do all thatstuff?

[notdustin97]

i dont think that would work

[moviemakers989]

duh, read the box at the beginning.

[Slickdc333]

I think it might be possible to create a real lightsaber, but it would not function as it does in the movies.

[VegasSpartan]

The problem inherent to a lightsaber, or an energy sword from the Halo series (my personal favorite) is keeping the energy contained in a blade.

I can't think of any technology around that will keep it from either becoming a simple laser (the energy just shooting out forever) or collapsing and just kinda blinking out.

[SupremeCommanderO1]

the beam of a lightsaber is made from plasma

[VegasSpartan]

Right, but how does it stay condensed in a blade form? That's probably the biggest issue with making a lightsaber work.

[SpeckerWrecker91]

They have and continue to perfect the method of making working, lightsabers in Canada; the problem, surprisingly, is NOT keeping the energy contained in a blade-style but rather powering it.

To simply start-up and power the small blade for a short time requires, with our current technology, a generator as big as an average classroom. That simply wouldn't fit on your beltloop.

[NoogahOogah]

The electromagnetic field.

[xSeancex]

how would you keep it as a sword and not let it shoot electrons at people?

[LETHALARMOR]

if you do end up doing this, and make one, i offer to be a tester lol, on some conditions,

1. i get a free lightsaber (of my choice_

2. i get discounts XD

[biohazerdfilms]

this is why you need a backpack with a batterie in it, then put a wire from the backpack to the hilt, and how would you get the color? and i dont think electrons can cut through metal or humans :P

[DemonicFireFly117]

Alas, I never though the magnetic key was to focus a field from the hilt in that manor. But, how much power and care would this require? Can we make a hilt of sorts that can hold the energy needed to keep a lightsaber running for long periods of time?

[gundamVdbz]

my bet is... at best we would be able to make something capable of doing exactly what this shows.. but the power supply would definitely be depleted within 5 minutes

.. perhaps a self charging one, so after so long it shuts down and recharges

[bigouillecreation]

yeah u can make millions with this if it works

the army can use this

[DemonicFireFly117]

I don't think so. It wouldn't be very efficient in the military. In Star Wars the lightsabers can deflect blaster bolts and such, but bullets would be a different story. Although a bullet would surely burn up in a lightsaber's blade, it would be very difficult to hit the actual bullet. A lightsaber would function better as a practical tool for cutting, welding, and other things.

[gundamVdbz]

i agree, i could bet a Platoon of Marines would be able to Defeat a battalion of Stormtroopers... and more then definently a squad of jedi, .. Jedi are cool but when they cant see the Projectile coming... it may be dificult to stop a wall of it.

[pokezach100]

they can sense it coming at them

[bigouillecreation]

yeah buty if you remove the magnet this create a powerfull proton beam this can cut trought anything can be use to pierce tank armor or jet armor get it?

[masermaker97]

were you not whatching it first of all it uses ELECTRONS not protons and second it was explained that the bean length was limited because the electrons lose momentum and arc back to the hilt

[masermaker97]

I agree one could make millions but how much would it cost to make them and how many starwars fans have millions

[ilikewomen94]

You'd be surprised how many star wars fans would get one

[1AceMoneyMaker]

@ilikewomen94 and the halls of elementry, middle, and high schools would be drenched in blood :)

[bjggjb]

@ilikewomen94 I WOULDN'T be surprised at the large number of Star Wars fans who became self-inflicted amputees after they bought their real-life lightsabers and waved them around trying to impress the other geeks at the sci-fi convention.

[sovietspyguy]

Electron guns require high voltages and high currents, which necessitates the use of very large and very heavy power supplies (for powerful electron guns). An electron beam could kill someone, but it would not be instantly fatal and it would not be outwardly visible. It cannot burn or cut anything.

Any time an electron beam hits it produces a cascade of x-rays. Exposing yourself to the radiation produced by a powerful electron beam striking something like metal would be suicidal.

[masermaker97]

using that way of thinking wouldn't arc welders poison their users?

[sovietspyguy]

An arc welder is not the same thing as an electron gun, but they certainly do "poison" their users if they leave skin exposed for a long time. You can get UV burns, just like you do from sitting in the sun too long.

[OenKnows]

Lol sunblock for jedis

[jessmoblank]

dude u should try that and see if it works.....if it does then basicly ur rich(if ppl buy it)

[AeroSixWJ]

this does seem plausible to work. Now I wonder how the beam would cut through anything like a real lightsaber. would the electrons provide that kind of heat? Or would they just give you a serious burn like from a stove or something?

[catseye10000]

your forgetting one thing, your going to need a lot and I mean a LOT! of dam power to make it work, more than even a lithium power cell can provide

[ak4theside]

dude u could just by them and save time

[OsyenVyeter]

Good work about the repulser plates though. I had forgotten about those, it is another tv construction technique of course, but I feel that it has real application to the idea.

[OsyenVyeter]

Well its definately a good start.That design is basically what Ive come up with (though i never really gave it much thought though either.)I can see that this is about 95% based exactly on television technology.The only thing that I differed on was the use of a lens to make for a convergence point which is normal for photonic physics, but that whole magnet limiting the length of the blade sounds like a rather shaky premise if I may.Cool video though its definately good to throw ideas out there

[robybirdy]

verry interesting idea and an idea i came up with is getting little mirrors and like a bruning lazer and get some sort of frame and put a little mirror where you want the beam to go up to and have it come into another mirror wich is pointed at the other mirror and the laser keeps adding more and more heat and it gets more and more intense utnill the morror shadders :( haven't figgured that part out yet

[masermaker97]

but then they would just go through each other

[bfr666]

And when you try to battle with two of these, they repel each other so strongly it will fly off from you hand and gets stuck in the metal floor of the Death Star? :)

And would it anyway be more effective than a bar of steel? Or just cooler?

[nextgentech]

It's difficult to say how it would interact with another beam or with matter in general. My guess is that it would "cut" through matter at the atomic level, so it would be more effective than a bar of steel. Of course it would be cooler as well!

[JPRubber2]

Too bad these messages come up in reverse order. Anyways, this setup would only require that a magnetic field be parabolic and intense enough only at the tip of the beam, making the energy requirement for the field much lower. Not absolutely sure of he 'shape' of the reflective magnetic tip. Parabolic works well for reflecting light, but for quantum nanophysics, the mechanics may be greatly different. Resonant tuning and possibly a point of convergence would work better. Would love to try it...

[nextgentech]

Very interesting idea...thanks for your comments!

[JPRubber2]

I wonder if we could make a beam that spirals in extremely tight formation, a single resonating spiral only wide enough for electrons to spiral out to a magnetic 'tip/corner' and be reflected straight down the center of the spiral, esentially 3 electrons wide. Have to account for probability of size of the electrons, seeking out a critical energy density as the boundary to assign the 'size'. The spiral would cause the particles to follow a natural beam path, making magnetic tuning easier. hmmm

[JPRubber2]

hmm, first, consider the thermal energy to make this useful. It has to get HOT at least in some tiny line. So, spreading the beam would be undesireable. Your beam idea could work if the containment field is powerful enough. This is the critical hole. Takes a lot of energy. Unless the beam is tiny.. Think of the containment field as a balloon. You need 'pressure' to generate the beam intensity. More pressure requires stronger balloon. Which means a regulator would be needed...

[GamerShorts]

id also like to know some of the flaws because to me and my mate it sounds genious.

[nextgentech]

Well, for example, the high-velocity electrons would collide with the air molecules, which might produce gamma rays and other harmful radiation. Also, other magnetic fields may interfere with the beam.

[thundermoon96]

@GamerShorts what do you meen by mate???

[WonHalf]

may i ask what the flaws are? lool..

if like to have a lightsaber..

[2coolperson]

it's a genius design

[liamthespy]

wont they just fall apart as the saber moves?

[nextgentech]

The idea is that the electrons become "trapped" in the positive magnetic field. The electrons that do get lost are also quickly replenished from the cathode.
